DRIVE CONFIGURATION
Setting Operating Parameters
49
8. Decel Time [SET–12]: The time in seconds to slow down from maximum frequency to stop. Recom -
mended defaults are 2 seconds for submersibles and 30 seconds for surface/booster pumps. This set -
ting is only effective when
Stop Mode [SET
–
16]
is set to
0_Decel to Stop
. Additional deceleration curves can
be added for more precise control through selected frequency ranges. Refer to “Acceleration/Decelera -
tion Control” on page 80 .
9. Low Freq Limit [SET–13]: The lowest frequency (speed in Hz) allowed by the VFD in any mode.
10. High Freq Limit [SET–14]: The highest frequency (speed in Hz) allowed by the VFD in any mode.
11. PID Mode [SET–17]: Enables or disables PID control, either direct or inverse.
12. PID F/B Source [SET–18]: The input terminal for PID Feedback source. Be sure to configure the termi -
nal for the correct signal type.
13. PID F/B Unit [SET–19]: Selects a measurement unit for PID feedback.
14. PID F/B Max [SET–20]: The maximum reading of the feedback source. This is used to scale the analog
signal to transducer. For example: if using a 0–200 psi transducer, the value should be 200.
15. PID Set-point [SET–21]: The desired value for the drive to maintain in PID mode while running in Auto.
This parameter can also be changed through keypad on Line-1 of the display (value P).
16. PID Low Hz Limit [SET–22]: Minimum PID frequency output will be limited to this value.
17. PID High Hz Limit [SET–23]: Maximum PID frequency output will be limited to this value.
18. Language: Select a desired language for the display. Press the MENU button and then press the BACK
button. Use the down key to scroll to
5_Set Language
.
19. Clock: Current time and date. This setting is used to record real-time data for faults, parameter
changes, etc. To adjust, press the
MENU
button and then press the
BACK
button. Use the down key to
scroll to 6_Set Time .
Verify Control Terminal Settings
For each type of control hardware that has been connected to the system—sensors, switches, BAS, etc.,
make sure that the matching function parameters have been identified for the input terminals. For more
information, refer to
“Example Configurations” on page 43 or to “Parameter Descriptions > I/O Menu” on
page 209 .
Enter or Verify Optional Settings
